I'm not surprised that these records were badly photocopied. The photocopy machines they used in 1869 must have been difficult to operate.
Nah, these were photocopies of the originals made back when if one photocopied something, the black ink came out white, and the white background came out black, and repeatedly photocopied over the years.
I assume the 1950s, perhaps?
Of course this isn't Skins's island; no one here's old enough to remember when photocopies came out in reverse.
